// Form control sizing
//
// Build on `.form-control` with modifier classes to decrease or increase the
// height and font-size of form controls.
//
// The `.form-group-* form-control` variations are sadly duplicated to avoid the
// issue documented in https://github.com/twbs/bootstrap/issues/15074.

// Form groups
//
// Designed to help with the organization and spacing of vertical forms. For
// horizontal forms, use the predefined grid classes.

// Form grid
//
// Special replacement for our grid system's `.row` for tighter form layouts.

// Checkboxes and radios
//
// Indent the labels to position radios/checkboxes as hanging controls.

// Form validation
//
// Provide feedback to users when form field values are valid or invalid. Works
// primarily for client-side validation via scoped `:invalid` and `:valid`
// pseudo-classes but also includes `.is-invalid` and `.is-valid` classes for
// server side validation.

@include form-validation-state("valid", $form-feedback-valid-color);
@include form-validation-state("invalid", $form-feedback-invalid-color);

// Inline forms
//
// Make forms appear inline(-block) by adding the `.form-inline` class. Inline
// forms begin stacked on extra small (mobile) devices and then go inline when
// viewports reach <768px.
//
// Requires wrapping inputs and labels with `.form-group` for proper display of
// default HTML form controls and our custom form controls (e.g., input groups).
